The Bank of America Chicago Marathon announced today that four-time Olympic gold medalist, six-time world champion and five-time European champion Mo Farah will join the 2018 Chicago Marathon elite competition. In 2012, Farah became the first British athlete in history to win an Olympic gold at the 10,000m, and he is just the second athlete in history to pull off back-to-back gold medals in both the 5000m and 10,000m at the 2012 and 2016 Olympic Games.

The Chicago Marathon marks Farah’s third go at the distance and his first 42K on U.S. soil. He joins defending champion and former training partner, Galen Rupp, at the front of this years elite pack. Mo Farah and Rupp made history together at the 2012 London Olympics, finishing with the gold and silver in the 10,000m.

“Mo and Galen are two of the greatest distance runners of all time,” said Executive Race Director of the Bank of America Chicago Marathon Carey Pinkowski. ”They come to Chicago following in the footsteps of incredible runners like Khalid Khannouchi, Sammy Wanjiru, Moses Tanui, Paul Tergat, Steve Jones and more. These two runners have competed at the highest level of competition and Im confident they will come prepared for whats shaping up to be an epic showdown.”

Farah made his marathon debut in 2014 in London, clocking 2:08:21 to finish eighth. He refocused his energy on the track and the 2016 Rio Olympics before tackling the distance again this spring. He finished third in London with a new personal best and a national record, 2:06:21. Farah dazzled fans at the 2016 Rio Olympics when he experienced a dramatic fall, tumbling hard to the track, in the 10,000m. Instead of panicking, he found his feet, rejoined the pack and ran away from the rest of the field to win gold. In addition to his Olympic and world titles, he has landed on the top of the podium 20 times in the Diamond League track competitions.

Farah holds national track records in the 1500m, 3000m, two-mile, 5000m and 10,000m, and British road records in the 5K, 10K, 20K, half marathon and marathon. In 2017, Farah was named BBCs Sports Personality of the Year.
